OM3 Moulded Case Circuit Breaker (MCCB)
Detailed Product Description
OM3 Moulded Case Circuit Breaker (MCCB)
1.Application
OM3 series moulded case circuit breaker , it's applicable circuit of AC 50Hz(or 60Hz),ratedinsulation voltage 690V(OM3-125 500V),rated operating voltage AC 690V or below ,rated oper-ating current 12.5-1600A, for distribute energy of electric and infrequent making and breakingcircuit in normal condition. The circuit-breakers are provided with the function of the protectionagainst overload and short circuit and under-voltage. The circuit breakers comply with standardof IEC60947-2.The circuit-breakers are double insulating (Inm=250A or above), the controlcircuit of the accessories is set apart with the main circuit , and doesn't need to open the coverof the circuit-breaker when install the accessories.
